That's absolutely right, but doesn't explain why the jailbars appear in areas of solid colour. If the Amiga's video output was clean there'd be no variation in signal level over the duration of a pixel, and thus nothing to cause interference patterns.
How can you make the Amiga's video output cleaner? The single most effective way is to tie off that open unterminated clock signal on the video port. I did this on my A500's DB23-VGA adapter a few weeks ago and the jailbars are quite simply not there any more (at least in solid areas - obviously you can't eliminate pixel clock interference patterns unless your monitor's phase/pixel-clock settings are flexible enough to achieve a perfect sync.)
